Pilot Development of Linear Low Density Polyethylene High Speed Emitting-Pipe Special Material
摘要
Abstract
The technical specifications of emitting-pipe special materials were determined by analyzing a commercial emitting-pipe special material.Linear low density polyethylene(LLDPE),which was produced in a 50 kg/h gas-phase full-density polyethylene pilot plant,was blended to prepare emitting-pipe special material.To meet the requirement of high-speed processing,the optimum melt flow rate(10 min) and density of emitting-pipe special material were 0.3-0.6 g and 0.928-0.940 g/cm3,respectively.The prepared and commercial emitting-pipe special materials were characterized by means ofGPC,13C NMR,rheology and melt strength test.The results show that the mechanical properties of DGD-3 special material are the same as those of commercial Sabic emittingpipe special materials but DGD-3 has better processability.The emitting-pipe prepared by DGD-3meets the national standards,such as good appearance,tensile deformation less than 5.0％,burst pressure greater than 0.3 MPa and micropore water flow 3.3 L/h.关键词
